Question about training and etc.

I was wondering since i got the letter telling me what to bring, it says neatly trimmed facial hair and no piercings except modest ones in the ears. I dont have any piercings anymore but i do have tattoos on my arms. Nothing offensive but i was wondering should i wear long sleeves during training? Or should i not worry about it? it doesnt say anything about tattoos on the letter. I understand looking professional and i worked in a professional job for most of my career. I wore long sleeves at my job until they told me i didnt have to. which was odd. but i guess my tattoos are not really that out there. its just Japanese kanji on my arms. I was trying to grow a nice beard but i dont think it will be along far enough by training so i may have to shave and grow it OTR.

Anyways let me know what you think.

 

lol thanks guys.
